I took another look into it. I think if you are just working on the
source code transform,
you should be able to skip the evaluation step which short cut the typedef.

Can you try again with the same patch, but in your program, using
__sparse(filename)
instead of sparse(filename) to get the symbols? Using __sparse will skip the
evaluation step. It should keep the typedef node unchanged.

The back end only care about the type, not the name of type.
In fact, C type system need to evaluation the type to get ride of the
alias so it will not complain type mismatch due to typedef.
